Sims have no skin tone??

Haven't played as my original household in a while and decided to load them up. When I opened the game to the home screen, two of my Sims didn't have a skin tone. I went in and checked for any broken mods and found no solution. I've tried completely removing the mods folder, and the issue remains even without mods or CC. Tried repairing the game and removing localthumbcache and localsimstexturecache, and they're still messed up. Going in with cheats and trying to change the skin tone doesn't work either. If anyone has a solution, I'd appreciate it! :P
